SaGa Frontier is great...

...the first 3 times through. After about the third quest, it tends to get a bit repetitive.

The good news is, you can complete about 3 quests and stop for about a year, then finish up the other 4. Each quest is about 9 hours long. The most I've clocked on a quest is about 12 hours, and that was the final quest where I went all out with every side quest in the game.

It also has some of the best music I've ever heard in a video game.
